7 USE
Ensure the instructions below are followed to guarantee the correct operation.
Before starting any maintenance operation remove the electric supply using the
switch outside the unit. Then close the manual valves of the circuit’s object of the
maintenance.
Empty the parts that contain hot water before proceeding; this must be done using the
circuits connected to them.
The adjustment of the thermostatic/mixing valve cannot be altered by the end user; only
qualified personnel can do this operation.
Check periodically that no air is present in the circuit and eventually remove it.
Check the correct operation of control and safety devices at least once a year.
Before discharging hot water, make sure that the discharge pipe is connected to the drain
in order to avoid burning people or damaging objects.
All discharge pipes must allow air to flow through them.
If the safety group leaks occasionally, it could be due to materials expansion or valve clog.
Follow the instruction for pump maintenance.
Check the correct operation of valves, taps and electric accessories used.
At every maintenance operation clean the “Y” filter when present.
A clogged filter would affect the correct operation and eventually cause the unit to
stop working altogether.
Before starting any maintenance work on the unit remove the electric supply
using the switch outside the unit. This is because the unit is permanently
supplied, even when the external thermostat is off.
The ModuSat TP is provided on the front panel with a Manual/Automatic push button: in
manual mode the DHW valve is completely opened thus allowing DHW
production.
In manual mode no control of DHW temperature is possible and the water
temperature can reach up to 70 °C.
7.1 Maintenance
As the Modusat has no internal combustion, it requires a limited amount of maintenance.
There is no need for regular maintenance other than the annual inspection.
Only the filter,
when installed outside, needs to be cleaned at commissioning and when a flow
reduction is reported
. A flow reduction reduces the Modusat performance, although there
is no increase in the energy consumption.
